Abstract

Background: In conventional X-ray examinations, patients are exposed to radiation. Biological hazards from radiation of any source is expressed as effective dose, and is measured in millisieverts (mSv). The purpose of this study was to assess and calculate the effective dose values for patients undergoing posteroanterior (PA) chest, abdomen, anteroposterior (AP) pelvis, and cervical spine X-ray examinations in general hospitals of Erbil city and compare it with those of other studies. Materials and Methods: A total of 255 patients between 20-70 years of age participated in this work (85 per hospital). The patients’ characteristics included age, sex, examination type, projection posture, and exposure parameters captured by NOMEX Multimeter including tube potential and current-time product. The mean effective doses (EDs) of four different examinations (chest (PA), pelvis (AP), abdomen, and cervical spine) were measured using the Monte Carlo method and compared with those of other studies. Results: The mean EDs were calculated 1.04, 2.01, 3.12, and 3.22 mSv for chest (PA), pelvis (AP), abdomen, and cervical spine, respectively. All ED values in this study were higher than those of published studies. The aim of the study was to increase the awareness of the radiographer and patients undergoing conventional X-ray diagnostic radiology on the risk of ionizing radiation for radiological protection in Erbil hospitals. Conclusion: The mean EDs were increased by an increase in the age; this may increase the probability of cancer incidence and heritable diseases. Hence, dose optimization is required due to more probable incidence of cancer when compared to other studies.

Highlights

Diagnostic X-ray is a known diagnostic practice, and the number of examinations by it has increased recently [1], despite an increasing risk of ionizing radiation to human being
effective doses (EDs) were measured for 255 patients who underwent X-ray diagnostic examinations in public hospitals of Erbil
Patient characteristics and exposure factors were entered into the software for the measurement of ED values

Summary

Introduction

Diagnostic X-ray is a known diagnostic practice, and the number of examinations by it has increased recently [1], despite an increasing risk of ionizing radiation to human being. Effective dose (ED) can be measured using the Monte Carlo method for estimating radiation risk of irradiative field during the investigation of many organs and tissues that are exposed to ionizing radiation during the imaging procedures [9,10,11].The aim of this work was to estimate the dossed values of adult patients in medical imaging centers during the conventional X-ray examinations of posteroanterior (PA) chest, anteroposterior (AP) pelvis, abdomen, and cervical spine in Erbil public hospitals, Iraq. The mean effective doses (EDs) of four different examinations (chest (PA), pelvis (AP), abdomen, and cervical spine) were measured using the Monte Carlo method and compared with those of other studies.
